A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.

The invention relates to a bag (1) made of a flexible wall, which bag is fitted with an inlet fluid line for introducing dissolution water, and with an outlet fluid line (121, 122) for extracting a solution obtained. According to the invention, the inside of the bag has a lower edge (13) in the overall shape of a V, the point of the V being further away from the centre of the bag than the arms of the V, the outlet fluid line opening into the bag as close as possible to the point of the V.

A peritoneal dialysis device includes a disposable tubing set that includes a fill line with a patient access connector at one end and a dialysis fluid receiving end opposite the patient access connector end. The device also includes a fill-side pressure measuring sensor attached at the fill end and forming a disposable component of the tubing set and a patient-side pressure measuring sensor located at the fluid receiving end. The patient-side and fill-side pressure measuring sensors are adapted for measuring pressure in the fill line at the respective ends thereof. The device also includes a controller configured to regulate a rate of flow in the fill line responsively to a signal from the at least the patient-side pressure measuring sensor.

The present specification discloses a dialysis system having a reservoir module with a reservoir housing defining an internal space, a surface located within the internal space for supporting a container that contains dialysate, and a conductivity sensor located within the internal space, where the conductivity sensor has a coil, a capacitor in electrical communication with the coil, and an energy source in electrical communication with the circuit.

A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

The disclosure relates to concentrate pouches for use in peritoneal dialysis. The pouches can contain a solid, liquid, or aqueous solution. Water can be added to the concentrate pouches to facilitate dissolution and mixing of dry powders and/or aqueous concentrates to generate a peritoneal dialysis fluid for use in peritoneal dialysis therapy. The concentrate pouches can include a venturi to assist dissolution of concentrates.

A dialysis fluid apparatus includes a flexible dialysis fluid container, a holder structured such that the flexible dialysis fluid container is held vertically within the holder and conforms to a shape of the holder, a pressure sensor positioned and arranged to sense a pressure of a fluid held within the flexible dialysis fluid container, and a control unit configured to (i) store at least one cross-sectional area of the flexible dialysis fluid container, (ii) calculate a head height using the pressure of the fluid held within the flexible dialysis fluid container, and (iii) calculate a volume of the fluid held within the flexible dialysis fluid container using the cross-sectional area and the head height.

A container system includes at least one flexible wall defining a compartment containing a dissolvable solid or concentrate, a support adjacent a first end of the at least one flexible wall, and a nozzle assembly coupled to a second end of the at least one flexible wall. The second end of the wall is distal from the first end. The nozzle assembly comprises a hollow body defining a longitudinal axis. The hollow body further defines a plurality of orifices through a wall thereof. Each orifice is able to form a fluid connection between an interior volume within the hollow body and the compartment. Each orifice is configured to deliver liquid from the interior volume to the compartment in a direction having an angle of between 5° and 85° from a direction of the longitudinal axis. Related nozzles and methods are also disclosed.

A treatment device system includes a treatment machine for performing a therapy on a patient, the treatment machine including at least one fluid conveyor and a controller, the controller having a first memory, to cause the at least one fluid conveyor to produce a therapeutic fluid by mixing purified water and at least one concentrate. The system also includes a water purifier with an internal central controller, in fluid communication with and providing the purified water to the treatment machine. A wired or wireless control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier, the controller of the treatment machine transmitting data via the control line to the internal central controller of the water purifier for control of the water purifier, the data provided based on at least one of the operator inputs received via the user interface.

A treatment device system includes a treatment machine for generating a custom dialysis solution and including at least one fluid conveyor, the treatment machine having a controller, the controller having a first memory, configured to produce the custom dialysis solution by causing the at least one fluid conveyor to mix purified water and at least one concentrate. The system also includes a user interface and a water purifier in fluid communication with and providing the purified water to the treatment machine, the water purifier including an internal central controller, the internal central controller having a second memory, to control preparation of the purified water. A server is communicatively coupled with the treatment machine and a control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier.
